  • Converting upper-case string into title-case using Ruby

    - by wsb3383
    Hi, all. I'm trying to convert an all-uppercase string in Ruby into a lower case one, but with each word's first character being upper case. Example: convert "MY STRING HERE" to "My String Here". I know I can use the .downcase method, but that would make everything lower case ("my string here"). I'm scanning all lines in a file and doing this change, so is there a regular expression I can use through ruby to achieve this? Thanks!

  • Function of: if(/(file|http).*/.test(url)) { }

    - by WmasterJ
    I am wondering what this technique is called and what it does. It seems to be validating some regular expression on the variable url. I am customizing another persons code: var url = document.getElementById("editorURL").value; if(/(file|http).*/.test(url)) { } Maybe someone has a link to an article that explains this a bit more in-depth?

  • Does this e-mail-regex exclude valid addresses?

    - by neo
    I tried to create a regular expression which catches all RFC-valid addresses but it's ok if some false-positives come through (though hopefully not so many). This is waht I came up so far: /^\b\S+@\S+\.[^\s@]{2,}\b$/ Is there any RFC-valid address which doesn't match against this expression or do you have any suggestions to improve it? I don't mind the false positives but I would be glad if you show me a few, too.

  • Can I do a reduce on a list comprehension into two lists, based on two values?

    - by pdknsk
    I've got the following code. sum_review = reduce(add,[book['rw'] for book in books]) sum_rating = reduce(add,[book['rg'] for book in books]) items = len(books) avg_review = sum_review/items avg_rating = sum_rating/items What I'd like is this. sum_review,sum_rating = reduce(add,([book['rw'],[book['rg']) for book in books]) items = len(books) avg_review = sum_review/items avg_rating = sum_rating/items Obviously this doesn't work. How can I solve this redundancy, without a regular loop?

  • How to track downloads from an Eclipse update site?

    - by Uri
    I have a plug-in that I am distributing via an Eclipse update site. I want to track how many times it is being downloaded, and preferably by whom. For regular pages on my site, I can use Google analytics. However, Eclipse doesn't use any HTMLs when going for update sites. Is there any way to do this when I don't have access to the hosting apache?
